AUTOMATIC APPARATUS FOR CLEANING TOBACCO-SMOKING PIPES.

Specification of Letters Patent.

Patented Jan. 23, 1917.

Application filed June 29, 1914. Serial No. 848,105.

provide an improved and simplified device of this character which is of such form and construction that it may be applied to the bowl of a pipe while tobacco is burning in the pipe and held tightly in position with- .out danger of burning the fingers of the operator.

Anotherobject of the invention is to provide an improved device of this nature wherein'a more powerful air blast may be' effected than is possible with devices operated by a person blowing through a tube pr. I

- from this glowing tobacco because of the the like.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel de tails ofconstruction and combinations of parts hereinafter tally described, illustrated in the accompanying drawings and specifically claimed.

In the drawing, the viewis a side elevation partly in section showing the improved device asapplied to a pipe.

In carrying out the objects of the inven tion- I provide, in the present embodiment, a circular metal casing or cell A of suliicient size to entirely cover the bowl of a pipe and the under side of this cell is provided 'centrally with a short tubular projection ----aintended to extend dofwnward slightly into the bowl and also form a support for washer a which is preferably made of leather or other elastic material. Extending from one sid efii the cell A is a tubebprovided adjacent its extremity with a bead bso that the end of a flexible rubber tube C may be fitted on the tube -band securely held thereon as shown. This tube G is connected to a syringe bulb B which is of the type which when compressed forces air through the tube G and when allowed to expand draws air in through the inlet c-. The cell A includes upper and lower parallel walls that provide an air chamber for storage of air that ice-filled therein by the bulb B and tube C, thereby providing a continuous pressure of air passing through the pipe P when the device isin operation.

In operation it is preferred that a charge of. tobacco be placed in the pipe P and ignited." The cell A is then placed in position as shown in the figure and the bulb B repeatedly compressed and al owed-to expand. This causes a flow of air through the short tube -a and brings the tobacco in the pipe P to a bright glow much hotter than the ordinary combustion eifected by smoking in the usual manner.

It is to be noted that the cell A canbe held in position by the operatorplecing his linger thereon wit'hout dangerof burning fact that there is a constant current of cool air flowing in the chamber between the upper and lower sides of the cell A thus maintaining the same cool in spite .of the intense heat from the tobacco. The intense heat thus generated causes amelting of the ceked products from the tobacco w ieh has been previously smoked in the pipe and at the same time the air current blows melted products out of the stem of such pipe.

There has thus been provided a simple and I forming a chamberwithin which air is compressed, an inlet tube extending into the tube being located entirely below the sur edge of thel cell, and a3 elastic wasllller lfitted face of the upper wall.

on the out et tu e an covet-in t e ower side of the pell to be seated on the u per edge I STANISLAUS E B of a pi e to prevent the'jesoape of air, said Witnesses:
